Page Problems - Images

My image(s) do not appear when my page has been uploaded.

1. Verify that you have uploaded your images - note on the OU system for T171 you have to upload each individual file. If they are not there upload them.

2. If your image files are on your site check your code it is probable that you are using absolute addressing and not relative. If your code reads something like <img src = "C:\mysite\image.gif"> then you are using absolute addressing change to relative addressing like this <img src = "image.gif"> upload your page again after making the changes and all should be OK.

My image(s) take forever to download

This problem is due to the size of the image(s) the larger the image file size the longer it will take to download. There are a few ways around this one:

For photographs: Make thumbnail image(s) of the photo(s) and place in you page - thumbnails are typically 100X100 to 200X200 pixels in size and download reasonably quickly, link each thumbnail to a new page which will contain the full-size photo - if the user wants to view the photo they wont mind waiting for this. I use this technique in the Canaries Holiday Snaps section of this site.

You could also try to optimise the photo by running it though JPEG optimisation software to increase the compression (make the file smaller) but this becomes a trade off between size and quality - the more you compress the greater the reduction in quality.

You could also try to save them as GIF files but be aware GIFs have only 256 colours so the quality of a photo would suffer significantly.
