Re: Can't get it to convert to PNG...

I've tried clearing the cache and evening manually deleting all the files in the cache with no joy - when I display a list of categories, each image is JPG.

The customer has commented that the images look a little blurred. I agree - I can see the JPG edge artifacts that you get sometimes and it doesn't seem to make a difference if I change the compression ratio.

I've got all compression levels to 100 (meaning best quality image).

Can somebody help me here?

Thanks,

Simon.

Check the host. We've had the same problem with GoDaddy versus another host. Quality improved on another host.

Any ideas?

Check to make sure your .htaccess file with the admin directory isn't corrupted.

There are a few hosts that block the ability to disable security filters via the .htaccess file.

No disrespect, but I don't really understand your reasoning.

Are you saying images are cached (in the browser) when someone loads the page?
Then that would be pre-loading...

What I don't understand is "defeat the purpose and functionality"...
isn't part of the purpose to have the hover effect load quickly?

If someone has to wait for it to load...THAT defeats the purpose.

Since it's very unlikely every image will be hovered immediately when the user hits the page,
having those hover images loading in the background would cache them locally,
making the effect faster...increasing functionality.

Or is "not feasible"...as in, it CAN'T be done?

As in it's pointless...the images are loaded as if they were placed in a regular image tag. There's not point in pre-loading them. The hover effect just, let's say brings them in to view. In otherwords they're already loaded when the page load completes, not just when you hover over them.

Pre-loading all the images wouldn't be feasible, or ideal.

My hoster had a serious problem with the chmod-command und always when i set permissions of the cache folder to 777 it was set back to 600. Emptying image cache and chmod with filezilla solved that. Now i have another Problem, I uploaded images and i get this error on the product-page:

Code:

Warning: preg_match() [function.preg-match]: Unknown modifier 'I' in /mnt/web7/21/67/51778667/htdocs/shop/includes/modules/clean_business/additional_images.php on line 47

I already removed double backslashes in the image-path through editing main_product_image.php but without any effect except the right image-path.

This is my additional_images.php in the /includes/modules/additional_images.php folder:
http://www.xup.in/dl,14463267/additional_images.php/

thanks for your help in advance :)

Any specific reason you've removed the "/i"?

Re: Image Handler 2 Support

The error was "Unknown modifier I" , so i thought removing it could help, but removing it changed nothing

Did you receive my PM? Removing the "/i" won't help and your actually killing the preg function.

What's probably happening here, is when your adding the product your instructing Zen to use an image already on the server. If that's the case, make sure your not putting a / before the image name.

In the meantime, I've written into your code a snippet to remove the forward slash. But to be safe, just don't use it.:lamo:

NOTE: Other images within your cart aren't showing, probably cause you haven't uploaded them yet. Just wanted to be sure your aware.
