Hi, Is there any way to specify the image width and height of thumbnails in the "cat" table? My category pages are loading very slowly and I think this will help a bit. I am using Interchange 4.8.6.
It won't help the page load any faster and newer browsers are pretty good at displaying the page as the images are being loaded even if it doesn't know the image sizes in advance. Older browsers such as Netscape Communicator will simply not display the page until all the images that don't have WIDTH and HEIGHT attributes in the tag are loaded. Note that in either case it does not affect the speed that the page or the images load in. At any rate:
Three ways I know of, all have thier good and bad sides.1. If all your thumbnails have the same dimensions and you know they will have the same dimensions for all future thumbnails, you can hardcode WIDTH and HEIGHT attributes into the IMG tags on the search results page. This won't work if your thumbnails have different dimensions.
2. Use an image library to load up each of the images as the image tags are being generated and display them. I highly recommend against this as it will put a very heavy load on your server's CPU and will slow down the page generation noticably. If enough people try to access the cat at once it could grind your server to a near standstill. You'd probably have to write a usertag to fetch the image off of the server's HDD and read in the width and height.
3. Add thumbx and thumby columns to your products table and store the width and height of the thumbnails in it, then the search results page simply has to put the values from these columns into the IMG tag as WIDTH and HEIGHT attributes. This requires a lot of data entry for all your existing thumbnails and future thumbnails but you can ease that burden by using an image library to grab these values and enter them in the table for you at the time the thumbnails are uploaded.
I'm not going into any details on exactly what steps you would have to go through for this because i just don't have the time to research it and figure it all out now, but this will at least get you on the right track.
