Check for image file, not there, display default blank.gif

[dmsid]

Like you I have thousands of products. We make the image file match the SKU number.

Product NT19432 has a picture file called NT19432.jpg that we have Shopsite create in three sizes.

Is there a way, Shopsite or Javascript, or ??? to look to see if the file exists on the server and if it does NOT exist on the server to display a file called blank.gif.

[if filename exists]
Do regular display of image
[else]
Display blank.gif
[endif]

Or just not display the file and do not display blank.gif

[if filename exists]
Do regular display of image
[endif]


This would reduced our [X] broken link images that are displayed when someone forgets to make a NT19432.jpg that is a blank. It would save a lot of time having to make these files for new products with no image.

And no we do not want to remove the ART#### from the graphic field, because when we do get an image we do not want to add data back in. New products are added from a datafile will all the pieces filled in ready to go.

All the best,

You can check if an image is assigned to a product by using [-- if product.graphic --] this will see if the database contains a value for the image. However, I don't think there is a way to see if the image actually exists on the server.

Well a simple check for file in the next release with an option in the images config would solve this. LOL

When you are on the products screen and try to save if you have an image assigned but the image doesn't exist you get an error. You can't continue until you either select a different image or set it to None. So the check is there already. If you upload your product information then this check is not done.

True, but we do all our major updates with Excel, even minor ones, so a check on the way out would be sweet.

That is why it is nice to be able o get under the engine on some software.

Also, if you are not using the dropdown menu for picking a file you can type anything you want there in the graphic name and it will not check for you as you save.

Thanks again for all your input.

If you're on a Linux/FreeBSD server with Apache, you could place a .htaccess file in your media directory with a mod_rewrite rule to display a default graphic when an image is missing. An example:

Code: Select all

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule \.gif$ /replacement.gif [L]

This will output replacement.gif for any .gif that is missing. You can add .jpg with:

Code: Select all

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule \.jpg$ /replacement.gif [L]
