Sizing Images

[Joe Germann]

I know that in Preferences/Images I can set the image sizes for all of the different types but I was wondering what the optimal sizes were and why images like xx_category.jpg had such a weird size (500x150).

The reasons for this query is that I am developing an application to auto-magically load and manage the database. As part of that application, we want to FTP the images to either a category (img/c) or product (img/p) area and will pre-size them for the xx-category, xx-large, xx-medium, and xx-small formats before being upload them.

Now, I must say that I find requiring multiple images of the same item to be a crazy requirement. I would actually like to load the actual image file rather than this ID_size.jpg naming convention and let PrestaShop auto-magically handle any resizing that is needed on the fly.

Does anyone know of contributions that handle images in a better way?

Any suggestions or recommendations would be appreciated.

Many thanks,
Joe
