Hello friends, I am working with images trying to improve the magnification and quality, question apart from photoshop, is there something not so expensive that I can use?

It doesn't work like it does in the movies.

X-Files had it right however.

And I have heard agencies say the solution was just a bigger monitor.
But for real,
Pretty all the image enhancement software I know of is paralleled with Photoshop.
Ocean Systems dTective
Foray
I played around with Starwitness Editor. Its a bit more technical and processing workflow based.
Photoshop now is subscription based. Like $20 to $80 a month depending on the license and package.
But video/image enhancement, you can only work with what you got. Sure you can smooth out the pixilation and adjust levels to make it more intelligible. But scaling an image will scale the individual pixels as well.
You always want the original format if possible. Work in a Lossless and no compression workflow. Retain an original copy of the image or video.
You can do some amazing thing with Visual Basic

Gimp is an opensource alternative to photoshop.
You can try VideoCleaner http//
VideoCleaner is FREE forensic video enhancement software created for law enforcement, and now available to everyone. Use any Windows computer to process digital images and nearly any video, including some proprietary formats, and VdeoCleaner includes a screen capture tool for everything else.
Or Focus Magic http//
Focus Magic uses advanced forensic strength deconvolution technology to literally "undo" blur. It can repair both out-of-focus blur and motion blur (camera shake) in an image. It is the only software that can significantly recover lost detail from blurry images.
Good luck!

Is it?
I would make an exception for those mentioned in the given thread

Hi there,
It’s difficult to assess exactly what you require, or what your original source data is, from the original post.
As has already been said, it’s vital that you are working with the native originally recorded material with no added compression or re-capturing.
Also, if you are working with Images originating from Video, then other considerations can be made to increase the overall quality of the enhancement.
There are two stages – Restoration & Enhancement.
Restoration uses a known mathematical model to reverse an observed defect. Deblurring for example.
Enhancement is a visual aid to assist the viewer in observing an image, or part of an image. Adjusting brightness/contrast for example.
The process of restoring, and enhancing, an image must attempt to reverse how the image was created (not always easy..and there are a few exceptions). If we identify the image creation path, and identify when a quality issue occurs, then we can attempt to invert this path, and therefore improve the image.
Magnification, using interpolation, is an enhancement process and is usually only considered after other defects are fixed (There are exceptions to this rule!)
There are a number of different filters for rescaling, and its worth testing each. From the classic Bicubic, to the more bespoke adaptive algorithms that are able to provide much cleaners results, given the right circumstance.
Regardless of what software is used, it must always be remembered that you cannot place something back into an image after it has been discarded through low resolution capturing or high compression. When it’s gone, it’s gone!
What you can do though is use software to assist you in rebuilding the pieces of the puzzle.
I’m the International trainer for Amped Software, developers of FIVE – Forensic Image & Video Enhancement. You were looking for something cheaper than photoshop, and we are purely for the investigatory field, so I won’t take you down a path that won’t help you…
However, when trying other software, consider how the image was created, think of the process you are using – it may just make a difference.
Good luck
