Hi,
I would like to ask for some advice how to resize pics in order to prevent horizontal scrolling in the forum. I have 15.4'' WUXGA screen on my ThinkPad and whenever I take a desktop screenshot or even only a partial screenshot with the snipping tool or export some office or pdf document as a pic, it appears quite huge in the post. For instance, I posted some table from excel: I converted the excel file to .pdf with settings for minimal storage size of the pdf file, then I cropped all the blank spaces out of the pdf and then exported the pdf as a .tiff image. All in all just under 7KB, nevertheless the image appears huge. When I tried to resize the .tiff image using paint, its storage size grew over 100 KB... So, my question is this: Is there anything that can be done to reduce the optical size of the image, yet keeping it under 56KB, so that I can embed the image in the forum?

If you host the image at http://www.imageshack.us/ there is an option before you upload to resize the image to a smaller optical size.

Ah true, great! Thanks a lot, Gom! That worked.

EDIT: I spoke too early. I tested this in my last post (the antivirus comparison) and when I checked the image size, it is now over 200 KB :(

Using the popular Irfanview, it has many options to resize a picture. http://www.irfanview.com/

Indeed, I photoshopped it a bit and the trick turned out to be resizing the image without resampling it. Of course, it is not the same quality, but it is still readable.

Thanks,

Marin

Well, yes, that is the easiest way, but that was not the point. If it was, I wouldn´t have asked, would I.

I'm using Photoshop to change Image size (Ctrl+Alt+I)
And Save for Web to adjust the compression (Shift+Ctrl+Alt+S)
