I have several images which are generated by using PHP + GD. They consist of a background image, and colored lines drawn on top of the images.
As the possible combinations depend on the behaviour of the final user, this must necessarily be a dynamic method of providing the images.
The URL would then be:
How would it affect SEO if I try to make an Image-Sitemap of several of the most rendered images?
Should I save the images in a static format, something like
SEO-Friendly-Name-Derived-from-parameters.png or Google and other search engines did not care about the image file not existing at all (first case) and would use the alt and title parameters ?
Note: these generated images are all hight quality images, because they are simply the diagram of components of the product. With each piece which is important (seo name of the file) highlited in other color. That means thousand of combinations of images, which I can, in any case, draw once with PHP + GD + Mysql and store as physical files.
