i have a website, and i'd rather keep the topic of the website out of this, and i want users to be able to paste an image URL into a program/generator and then the image will be added to a slideshow which moves onto the next image every specific amount of time.
the purpose is to display an image on the homepage, and it change automatically at a set time limit to another photo which someone has submitted.
if there is any way to do this, or any more efficient ways, please let me know.
i must also add, i am only using google sites do develop my website although it is live on the internet as a .co.uk website. i apologise if this post is in the wrong section
You are going to be "hot-linking" to other websites ... displaying their photos on your site.
Not only unethical, but in some cases, if the site has hot-linking disabled, your photo
won't appear (only a box with an X in it).
If you have users upload their own photos to your site, that would be a totally
different situation. You want them to provide URL's to photos and then display
them on your site.
Give me the URL to your site and let me hot-link all of your images to my site.
I'll show you how quickly I can destroy your bandwidth.
Maybe he doesn't mean hotlinking but linking to an image that is then submitted to his own database (and only downloaded from the source once). That would be totally fine but I'm not into that kind of coding, I'm more of a graphical guy so someone will have to point you in that direction.
If this is legit, then you could use server side and a database(php and MySQL). Then once the user uploaded an image(using a SQL insert query), then using a SQL query you could display the images. I guess you could use some javascript to loop through the images at specified time intervals, or even display them using a canned image gallery script.
