thankyou for your answers... but... is there any more complete definitions on the JPEG header standard?? &nbsp;i looked at <a href="http://www.obrador.com/essentialjpeg/HeaderInfo.htm" rel="ugc">http://www.obrador.com/essentialjpeg/HeaderInfo.htm</a>&nbsp;and it didnt cover a lot of the headers adobe uses when creating jpgs... <br />
<br />
i just need to create a program that extracts the width and height details from image files (jpgs in particular)

i need to be able to recognise an image and process it accordingly by looking at the header information in the file.<br />
<br />
therefore, i need to know the exact format of each image file header... is this information available in a simple format anywhere??<br />
<br />
a text file outlining the exact byte format would be great.<br />
<br />
i only need the format the header of jpg, bmp, pcx and gif files (all types).<br />
<br />
thanx

Websites use graphics to enhance information, assist navigation, and generally improve the user’s experience. To create those graphics, developers use any number of programs, like the Adobe Creative Suite (Photoshop and Flash have their own topics), the CorelDraw suite, Xara, Gimp, ACDSee, Serif, ULead and others.
