James,
I got even closer some minutes ago.
My relationship to ERAttachment is named "erAttachment", so I used an ERD2WDisplayImage component with the propertyKey "erAttachment.webPath", like:
100 : pageConfiguration = 'ListImage' => displayPropertyKeys = ("erAttachment.webPath") [com.webobjects.directtoweb.Assignment]
100 : ((pageConfiguration = 'InspectImage' or pageConfiguration = 'ListImage') and propertyKey = 'erAttachment.webPath') => componentName = "ERD2WDisplayImage" [com.webobjects.directtoweb.Assignment]
But webPath is not returning the full path, only the filename portion. This is what I get in the HTML:
<img src="" id="erAttachment.webPath">
I'll be looking at the screencasts suggested by Ramsey, since I want to create something like an "image grid" component... I'm gonna need a custom component anyways.
Cheers,
Flavio

Funny -
I was just looking at this issue. I was hoping to use the path as mine is not stored in the database: imageAttachment.s3Path
I tried ERD2WDisplayImage but didn’t understand where to set the “src” property since it wasn’t from the d2wcontext
then ERD2WDisplayImageWithUrl seemed perfect.
but ERD2WDisplayImageWithUrl gave me an error on my page:
error on line 191 at column 22: StartTag: invalid element name

You need to create a component. The getting started screencasts are good. Especially the ones David LeBer did (WebObjects, WOLips, and Wonder part 1 and 2). He got me started.

Creating the component should be relatively straightforward. The tricky bit is you need to generate the thumbnail. ERAttachment has code to do thumbnailing, but it doesn’t do it by default unless something has changed lately. It even has multiple image processors to give you native speed on some platforms. I think you will probably need to set up a attachment delegate to create the thumbnails yourself.
This would make a really nice example project for ERAttachment, but as far as I know, nobody has ever put one together.

Hello, all!
I took a good look at the online documentation and searched the list, but can't find an answer.
I have an entity called Image with a to-one relationship to ERAttachment. It works perfectly: i can add, edit and delete images. I can even see the image in the ERMD2WEditAttachment component.
Now I want to display a thumbnail of the ERAttachment in the "ListImage" page. I tried some components, but I can't make it work. The best I can get (using ERD2WDisplayAttachment) is an icon with the file name which, when clicked, will open the image in the browser.
Is there a ready-made component that does that or will I have to create one? If I'll need to create one, is there a foolproof guide to component creation?
Cheers,
Flavio
