Hello Edwin

You can specify the code for an image in the database.

You can see an example here : http://www.bramminginfo.dk/brm20/tur-optagelser.html

And another here : http://www.bramminginfo.dk/brm09/side-10.html

In the last example - if you go to page 2 and hover the images you will see two different hover-effects.

The first two gives another image when hovering, and the last 2 gives a gif-image when hovering.

You will this way have the images in one or more folders on your server, and then you specify the links to the images. You can use images in "normal" size and specify the showing in thumbnail-size by using the height or width option.

A much more advanced way is, that you can use a database tool as AppGini.

This gives the possibility to have images in fields and specify them directly with thumbnail sizes : thumbnail size in tableview, thumbnail size in, and full size by clicking.

If you here : http://eksempelsite.dk/biler/Biler_view.php?Embedded=&SelectedID=4

Click on  Biler detail, then you will see 

a table where you can click on a record and then see also the detail view.

This is made without any coding at all. Just by specifying some tables and upload the result.

You can see another example here : http://eksempelsite.dk/side-4.html

This page is without images - it is only to show the integration in X5.

It is done by using iframe.

If something of this is what you ask for, then make a post, and I will tell how it is made.

Kind regards

John S.
