Okay, I apologize in advance, for posting this, but I wanted anyone interested to see this. . . .

I work in multimedia for computer/web based learning applications, and I deal with a lot of graphics. In fact, part of the responsibilities of one of my past job roles was to set file size allowances for graphics, based upon their expected delivery connection. This just means that I set a maximum file size limit (KB), for a specific size resolution (pixels), given the expected connection speed. The goal is to achieve a good size-to-quality compromise.

Anyway, when it comes to webpages, such as photo galleries, graphics eat up a lot of bandwidth. This is not really bad for anyone with Cable/DSL or higher connection speeds, but the current average user is still on a 56.6kb/s connection, which means that a page full of graphics will load VERY SLOWLY.

I have to explain something else: A graphic file can be one file size, such as 320 pixels by 240 pixels (320x240), but a web page can display it in any size. (This is why you may often see photos that are stretched out of aspect ratio, or small graphics stretched and 'pixellated' into a larger size.) My point is, if you have a 400x300 graphic at 60KB, and you display it at 120x90, it is still the same filesize of 60KB. This means that it will still take the same amount of time to load (a lot).

On to my point>>>>I wanted to post this, so that anyone making a photo gallery webpage will take the time to resize and/or compress their graphics, to be considerate of those on slow connections. Also, a good way to go would be to make a page of thumnails, which link to the larger photos, so that those who wish to view a certain photo will wait for it, but everyone else is not burdened with a long wait.

There are several applications which will make thumbnail, or "contact sheets" for you, such as Thumbsplus ( www.cerious.com (http://www.cerious.com) )or ACDSee ( www.acdsystems.com (http://www.acdsystems.com) ). I'm most familiar with Thumbsplus, and ACDSee is about the same. They both have trial versions which can be downloaded. I think Ulead's SmartSaver makes thumnail pages as well, but I haven't used it. Also, Photoshop/ImageReady has a built-in webpage-maker, and a trial download, but it's very expensive. --If you use PhotoDeluxe, it's a stripped down version of P-shop, so it might be in there. PaintShopPro may work, but I don't know. There are probably some shareware apps out there, but I don't know of any to recommend (plus, you have to beware of "spyware").

Now, if you just want to learn some web stuff, I recommend www.webmonkey.com (http://www.webmonkey.com) , and www.webdeveloper.com (http://www.webdeveloper.com) , and www.webreference.com (http://www.webreference.com) .

Lastly, if anyone has any questions for me, either Private Message me here, or you can email me directly at heater451@hotmail.com. I can also just make this stuff for 'you' (with automation, it only takes a little while) if you wish to send graphics to me, but I was shooting for the "teach a man to fish" concept. . . .

Thanks for the advice, heater451. I have DSL so the pages load fairly quickly. I had forgotten what it was like on 56kb/s. I have photo deluxe, I'll check and see if it has a web page maker. I haven't run across it, but really haven't looked either. I'll do some reading and see if I can't learn a little. Most of what I do is just trial and error. I appreciate the help. I have exceeded my bandwidth allowance a few times already. Maybe this will help with that problem. /ccboard/images/icons/smile.gif
