Location: Indiana | generally, if you resize to 800x600 or 640x480 then it will upload and will also prevent those that view it from having to scroll-scroll-scroll to see it if their web browsers are set to view unscaled...
even 320x240 is often good enough for web site forums... |

Location: Indiana | as an understanding of "pixel size" (resolution) versus "file size" (kb, kilobytes) -
a picture that is 800 pixels wide by 600 pixels tall has 800 times 600 equals 480,000 pixels...
the "k" in kilobytes is 1024, but for a rule of thumb people generally just call it 1000...
480,000 divided by the "k" gives us 480 - so a 800x600 picture is 480 "kilobytes"...
IF the picture is "lossless" - but gif's and jpg's are "compressed", so they have a "loss" - but let's not muddy the details too much...
so when people point out 100kb or 250kb picture sizes, they're talking pictures way smaller than 800x600...
a 320x240 would be approx 77k
a 640x480 would be approx 307k
it's not "exact", but a rule of thumb...
basically, if you want to upload pictures, you do NOT want a "megapixel" picture from your camera...
a SMALL and CHEAP digital camera could take a 3.1 "megapixel" picture, or 3.1 *million* pixels when most forums only allow an upload of that divided by 30 THOUSAND...
we've all made it as clear as mud, eh?

Location: Netherlands | You mostly want to use a resizer-program where you can adjust the quality of the JPG, and saves the JPG for web-use. It will then leave out some irrelevant data inside the JPG which makes it even smaller and quicker to load.
I usually have no problems sizing pics back to 1024 pixels wide and still have them smaller than this site's upload-limit.
Some less-ancient forum-software than this sometimes has the (optional) functionality to simply resize the uploaded image before it gets stored and posted in the topic.
I've uploaded some image-size examples below to view;

(0640px.jpg)

Attachments ---------------- 0400px.jpg (44KB - 304 downloads) 0640px.jpg (102KB - 295 downloads) 0800px.jpg (152KB - 303 downloads) 1024px.jpg (238KB - 314 downloads)
