Re: Resize thumbnails with GD

Hi,
This is because there is no $tmbn_url
Try to add it .

Unfortunately, the above code displays no image :(, however, everything else seems to work just fine. Thanks for the post!

Yes, you can change the values by editing "include/lib/phpunsharmask.php" file. Search for the following string:

PHP Code:


		
			
function UnsharpMask($img, $amount = 120, $radius = 0.4, $threshold = 1)    {

xplorer: is it a way to configure those values in the Admin? A form inside the Mod?

No. The only way to change these parameters is editing the file I mentioned

Maybe someone will customize the script and have this feature available for an easy configuration.

I seem to be having trouble with this, I have performed the steps several times but it just doesn't seem to be working, not sure what else to try, I have tried placing the imagcache folder in different places but to no avail.

The instructions are so simple but it just doesn't seem to work.

Nice spot but I only spelt it wrong here.

Re: Resize thumbnails with GD

OK, so I found the problem

{if $config.Appearance.show_thumbnails eq "Y"}<img{if $id ne ''} id="{$id}"{/if} src="imager.php/product_thumb.jpg?width={$image_x}&image={$tmb n_url}" alt="{$product|escape}"{if $show_border eq "Y"} class="ProductBorder"{/if} />{/if}

This line had a / before imager.php so read src="/imager.php/product_thumb.jpg, I removed the leading / and all is working fine now.

Great mod, will really help me as I have 1000s of products.

Re: Resize thumbnails with GD

cool mod, I think its working, I saw a bunch of small files in my imagecache folder.

Couple questions for all you smart people in here:
Is there a way to just get rid of the option of a "product image" since the product thumbnail upload does everthing and there is no need for a thumb and a product upload?

This one I really need:
Can we cap the max image size either height or width so ALL the product images would be same height? (or width) that shows up in the main product details page? I'm afraid some of these providers are going to upload huge images. (too large on screen) Need to have it re-make them to a uniform size. (I think 4.2 can do this, can we do it in 4.1.11 somehow?

This would be huge for me, very much appreciate your thoughts on this.
