image processing in web server properties

I will do an image operation. The data here will be recorded in the database. For example date, number, location data.. Here, the algorithm results (data-numbers) I extracted from the images are sufficient.

In this context, my questions for the advanced situation beyond image processing theory are:

• Does each image or gif-video files consisting of images have to be uploaded to the server? if yes why
• Is it sufficient to assume a standard website features (disk- ram - processor speed etc.) criteria for the server or is a separate calculation required?
• Processes (image reading-analysis) are likely to be slow, but what can be done extra on the web server - site side?

Apart from these, if you have suggestions or questions, let's learn and develop together
