Okay, just a few ideas here for a starter.
This will only make a picture LOOK smaller, in height and or width, not really make it smaller, and no effect on the bytes of the picture.
Your picture you had was this.......
If your right click on it, you will see it is over 41K and 480X640. Both over the limits. Up in the FAQ thread from Mary Jo, there is a thread link as to the permitted dimensions. Less than 400X400 and under 35K.
To make it 400 wide, you would do this, using html <>, not UBB []........
<img width=400 src=http://photos.imageevent.com/kpoelzer/weddingphotos/photosbydawnpeake/websize/Pritchard%20Wed%200513.jpg>
You do need one space after the img and one after the size, 400 here. If it is on two lines, it is just word wrap, those are the only spaces, those two, and you would get this...........
<img width=400 src=http://photos.imageevent.com/kpoelzer/weddingphotos/photosbydawnpeake/websize/Pritchard%20Wed%200513.jpg>
Still too high though.
So, to make it not as high, you would do this.............
<img height=400 src=http://photos.imageevent.com/kpoelzer/weddingphotos/photosbydawnpeake/websize/Pritchard%20Wed%200513.jpg>
and get this...........
<img height=400 src=http://photos.imageevent.com/kpoelzer/weddingphotos/photosbydawnpeake/websize/Pritchard%20Wed%200513.jpg>
The other dimension, not stated, follows in proportion, only state one.
The picture still is over in bytes, but the size is okay.
The picture I made up earlier today had to be redone in a photo edit program (I use mostly Microsoft's Digital Image Pro 9 and sometimes Adobe's Photo Elements 2) so as to make the bytes less than 35K.
Have I confused you??
