I'm creating my own CMS, and I have to handle images with differentes sizes.

I store all my image's information in a database. For every image, I have:

• a filename (with extension)
• a title
• an alt attribute
• dimensions

Images can be used in different ways:

• cropped
• tiled
• exact dimensions
• only one dimension (for example: 200px height and auto width)

Right now, my URL to this images looks like this:

http://example.com/uploads/{id}/{mode}/{size_x}-{size_y}/{filename}.{ext}

A real example:

http://example.com/uploads/tile/24/200-200/my-picture.png
http://example.com/uploads/crop/24/200-200/my-picture.png

In my HTTP headers, I added a Link header, like Link:<http://example.com/tile/24/my-picture.png>; rel="canonical", which avoid duplicate content on images.

The URL is quite long. But I need all the informations provided in it.

Is it a problem for SEO? What are the solutions to optimize SEO for multiple-sized images?
