downloading a .gif

[Marc]

Hello,

I have a page with lots of thumbnails of photos. I want the user to be
able to dload a big version of the photo (also present on the server)
by either

1) clicking on it (left mousebutton) and have a 'save as...' dialog
or
2) right-clicking on it and have a 'save as...' dialog. But I don't
want the the whole photo to dload to the user before he is able to
rightclick it.

displaying the big photos as thumbnail and then right-clicking them is
not an option since it takes ages for a page with thumbanils to build
up...

I am not sure if 1 is possible and not sure if 2 is possible... Can
anyone give me a hint?

thanks ,

Marc

So, you want the user to be shown an image that is neither a
thumbnail nor has been downloaded to his computer nor is the full-
size image?

I think if you examine what you're asking for you'll find it's not
just impossible, but totally illogical as well.

Marc,

he wasn't insulting you, far from.
He was just pointing out that what you want to do -based on your description
- is basically impossible.
How do you want to show the user a site with images, if you don't want him
to download any at all?
Size is irrelevant, the fact that he is not meant to download images as you
describe it, make it impossible.

He was only asking you to re-read what you wrote and think it over again to
see where your logic fails.

If it's not deprecated, HTML has a tag for images lowres that should allow
you to download any image in a low resolution for quick display .. once all
images are loaded they will then be shown in full resolution.
Secondly, you could make doublets of your images, one in fullsize and
resolution and then a standartized smaller one for thumbnails. Which seems
to be what you seek ...
Then, building the image pages with thumbnails and loading it with lowres
should actually load those pages very fast and show the initial images.
Once the initial page is done, the images are shown full resolution for the
user to click on each thumbnail to get full size and full resolution
images.

... but still, he was only telling you about the flaw in your logic.

Not it doesn't if you don't build the thumbs every time. Lets say you have a
directory images/. Create two more inside, 'fullsize' and 'thumb'.

On each page load you check if the requested image exists in images/thumb/,
if it doesn't, you create it and store it there. As you add new images to
images/fullsize/, thumbs get created when requested, no additional
overhead.
