Re: [PHP] GetImageSize Problem
You can get this information from header of this image file. Structure of BMP is here: http://www.dcs.ed.ac.uk/home/mxr/gfx/2d/BMP.txt (found with google.com) M.N. --- [EMAIL PROTECTED] wrote: Hello, I'm PHPer from Korea. I have a problem with GetImageSize function. I wanted to know some information about BMP image. So, I tried to use GetImageSize on PHP 4.0.5 , Linux. But, it didn't work. GetImageSize function returned nothing. Then, I tried it on PHP 4.0.6, Windows2000. Ooops.. I worked.. -.-; I looked the php.net manual, but there's no mention about my problem.

I had a look at this problem in the plane coming back from Europe yesterday. There is definitely a problem in the code. The php_handle_jpeg() function is not hitting the right markers for some reason. My brain was too oxygen-deprived to see the cause, but I will try to get to it. As a workaround for now I suggest you use the read_exif_data() function instead. Compile using --enable-exif. That will definitely get you the right dimensions along with many other properties. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] GetImageSize() problem...
I think that was the first thing I tried. It might have something to do with the actual image itself. Images created with th PHP/GD routines come up with acceptable results.

Re: [PHP] GetImageSize problem
Hello! First - some ISP block you from get files from their server by a httpd request (that is what php does... I think!). To be sure if this is set or not, in the other ISP (not the one that the images are) write a simple html like this: htmlheadtitleloading images between servers/title/headbody brbr img src="http://Domain/ImagesDir/ImagesName.gif" /body/html In "http://Domain/ImagesDir/ImagesName.gif" be sure to put the correct domain and location of the image. This should show the image... If not you could have two problems: the link is wrong or the filter is set. Imagine this - I have a web site in an ISP with my domain like: http://www.mydomain.com and all the paths are gting the images from a free server like geocities.com so I don;t expend money on buying large amounts of bandwith for my site... If you think this way you know why they do that. if this works, just use thi path "http://Domain/ImagesDir/ImagesName.gif" in all your scripts for getimagesize... I expect that this helps.

Re: [PHP] GetImageSize problem
If you relly don't like the text jumping you can do a little script
that can parse the width and height for each image, I mean get this info
from the html files... But you will have to pin point each one... The good
thing that the script is here...
