Image Compression Problems

[stuffedhippo]

The image compression in the default theme banners is dreadful and also the module Home Text Editor. Load up images under themes and the are compressed way to far.

 

This is not a problem for the products images as there is a BO setting for these.

I have the same problem.
I want to upload my company logo to prestashop theme / template as "logo" but the result is really unacceptable for text.
My original logo is sharp, 250 x 80 pixels with about 18 kb while the resulting imported picture is same size with 6 kB.

No difference depending on the format wether png, jpg, gif, bmp is used.

 

Can this be turned off any way or is there a manual way to put this picture somewhere ?

I think this is not a new problem - are there any designers in the development team or just programmers ?

 

Sorry - but this is a nogo for a logo.
Looks very blur and unsharp.

So as the thread-opener didn't get an answer after 6 month I will publish my workaround.

After upload of the logo image in the backoffice (preferences->template) you may overwrite the result in images folder of the shop installation - it is marked with a number and this filename probably stored in the database.

Override this file hardly via ftp with the desired quality will replace a high quality image instead of the compressed one - size in pixel (width/height) should be the same of course. The new pic with high quality is delivered then through prestashop rendering or better will be loaded from the customers browser.
