So if you need professional images, but you don’t have the necessary resources to invest in a photographer, I recommend that you keep reading, because today we are going to talk about several important details about different stock images.

What are stock images?

Stock images are files that you can buy and download on specialized websites.

Usually, these are royalty free stock images,  or are offered for non-commercial use. You can use these images in your articles, in the design of your website, your posts on social networks and, of course, in your newsletters.

As explained before, there are stock images of two types: free and paid. The latter will often offer different packages or monthly plans, that is, you can download a certain number ofimages, depending on the plan you have contracted. In the case of free systems, the number of downloads is usually unlimited, although the quality of the material is not usually as high as that of  paid stock images.

As for image sizes, usually you will find different options: small, medium, large, for web Or vectors (.psd or .ai), allowing you to work with the files using advanced image editors, depending on your needs.

Another important point to note is the formats of the files which You can download from a stock image. Usually, in addition to these, many times these services also offer other features such as videos, gifs, icons or freebies.

How can I find stock images?

Here’s a review of the different stock image options available on the Internet, depending on the type of content they offer.

►Free stock images

First of all, I’ll talk about free stock images, where you can download and use images for free.

I would like to mention three well known options: Pixabay, Freepik and Unsplash.


Pixabay includes more than 940,000 high-quality files grouped together in three categories: photos, vectors and illustrations.

All available resources are free of copyright under license Creative Commons CC0, which means you can download, modify, distribute and use them for free, even for commercial purposes, which is good if you can’t work with paid images at the moment.



Freepik is one of the popular vector graphics for vectors, PSD and icon files.

On its platform, you can find different types of content and formats: backgrounds, logos, cards, infographics, banners, brochures, etc.

Freepik is known for offering creative and colorful designs, which always ensures very satisfactory results.

Please note that this platform has two versions: A free version  for certain features and another paid, for unlimited access to the stock images.


Founded three years ago, Unsplash has become a community of high quality photos. Their photos are available with Copyright using the Creative Commons license, which means they can be used for free.

On the platform, in addition to beautiful photographs, they also offer collections of images, where you can find the best option for your marketing strategy.

If you prefer not to work with free images, we will talk about paid options. In this sense, we will talk about some of the best known options:


123RF has more than 77 million royalty free images. It also includes other sections with different contents, such as videos, icons, banners, vectors, infographics and audios.

Some recommendations when using stock images

Although these images are a very useful feature, you should take into account a number of considerations before using this type of system:

  1. Don’t overdo it. The reality is that these images are not all 100% “real”. That is, if you have a company and an  “about us” page, if you use a file from one of these websites, the result will not be as realistic as if you were using an image of the members of your team.
  2. Always try to use the same type of images. If you decide to use these images, on your site or blog, my advice is to use always the same type of image to follow an uniform line.
  3. Add a personal touch to your images. So that the images don’t look so “unreal”, we recommend following these tips: You can apply a filter or effect in Photoshop to use your corporate colors, add a watermark or include your logo on the images you will be using.

How to decrease the size of the images you will upload in your newsletter?

When you work with images on your website or blog and also when you want to include these files in your newsletter, we always recommend that you select high-quality images. Remember that images are a feature that can help convince the user to visit your website, so he will remember your brand.

In this sense, the best option is to use images that are of good quality, but the major drawback of this strategy is the size of these files, which will increase download and upload time.

Therefore, you should prepare your images before uploading them to your website or for your newsletter, in order to reduce its size, but maintaining its quality.

So I’m going to list a number of tools and resources which you can use to compress your images.


If you use Adobe Photoshop to work with your images, you should know that there is an option to save images in web format, with the correct resolution for the size you need, but with a smaller file.

The “save to web” process in Photoshop is as follows:

  1. You should open the image on your computer. In the “File” menu, you can select the “save to web” option or use the following combination on your keyboard: Alt + Shift + Ctrl + S
  2. Next, a window will open where you can select some parameters to save your image: file name, format (.jpg, .png, .gif), colors or size. The latter is one of the most important aspects.
  3. The next step is to select the dimensions of the image. The width should not exceed 600px if you will use the file in your newsletter and 900 or 1000px if you are uploading the image to your website or blog. My advice is that you always try to adapt these measures according to your specific needs. When you add the width, the software automatically changes the height.
  4. Now that your image has already been properly optimized, it’s time to save it to your computer. is an online tool that allows you to compress and optimize your images before sending them to a website, blog or newsletter.

This tool supports four different formats (JPEG, PNG, GIF and SVG) and two different formats for compression.

Its operation is very simple. To compress your images, you must follow these steps:

  1. Click on the “Try it” button and you will see a page like this.
  2. Here you can select on your computer the image you want to optimize, which will be loaded and automatically compressed.
  3. When it is done, you will see the size of the image before and after being optimized. Finally, click the “Download your file” button to save the image. If you want to compress other images, you just need to click on “Compress another picture “.
