Would you compress it?

I’m not sure if your post deals with how slow the site loads (I have cable and it was slow), or with the content of the red circle on the screen shot.

The site may be so slow because the DocType you use is English, yet you have code in your HTML that is not English. This is just a guess, but the "EN" at the end of your DocType at the very top of your source code stands for English.

Your graphics seem to be OK as far as size goes. I didn’t see any that were huge files being displayed at smaller sizes, something that will always slow down a site.

If you intended me to notice the circle and the resulting larger file size, note that the type of compression selected is for "documents", not web pages, yet still weird. I use Photoshop to optimize my graphics for the Web.

Hi SK,

The "Microsoft Office Picture Manager" feature is not exactly part of the Macintosh version of Office.

On the Mac you get that functionality in PowerPoint. You put a picture onto a slide, scale it to fit the max size for the slide. The use File
Save As using the file type of PICT (picture). Cick the Options button
in the save-as dialog box and you can choose file compression.

I experimented with a 208k JPEG that I inserted onto a slide from a file. I saved it to two files, both with compression at 72dpi (you can select dpi in the Mac version but I don’t see that choice in the Windows screen shot you put up). When I chose "best" compression the file size was reduced to 120k. When I chose "least" compression the file size was just 32k. So in both cases the file was substantially compressed. Obviously the compression labels are reversed in the dialog box, so that is a bug.

You can report bugs in the windows version to

I’ll send in that little bug of the Mac version, too.

-Jim

No, the file labels are right, they are just ambiguous.

"Best" refers to the FILE QUALITY, not to the compression. JPEG compression is "lossy;" it degrades the quality of the image. If you compress a JPEG again, you degrade it even further.

When the dialog box says "best" and "least," it is referring to picture quality, not compression rate. "Best" compression degrades the image somewhat; "least" compression degrades the image a *lot*.

Hi!

If the picture is already compressed, then probably compressors that have no pointer of size increase due to re-encoding, will output a larger file! You think this is a joke? No it isn’t. If you are talking about the encircled part of the image, it would be a good idea to put a link to the original tiger picture, and post your question to compression gurus at "comp.compression" newsgroup.
