How to Launch Image Temporarily Stored in Collection

[Phineas]

I have a Camera control. I have Gallery. I have a Collection.

The image is stored in the Collection and recalled to the Gallery. I need the ability to 'Launch' the image when the image is clicked on to review the image before proceeding.

I can't seem to get the formula right. I've tried several configurations in the OnSelect of the Image control, including the following; none worked: 

        Launch(ThisItem.Value)

        First(ThisItem.'{Attachments}').Value

        Launch(FormImageGallery.Selected.Value)       

        Launch(FormImageGallery.Selected.FormImage.Image)

@Phineas ,

You cannot Launch it as the command refers to "external" items accessible via a URL (your image is still in the image control or collection). You can however make a full screen Image Control Visible on a Variable with 

First(ThisItem.'{Attachments}').Value

or if in a Gallery

GalleryName.Selected.Value

and you will be able to review the picture.

Can you please clarify "You can however make a full screen image Control Visible on a Variable..."?

I can already see the images in a small version in the image control.

How would I apply your fix so that when I click on the image control the image opens in a large web view?

I tried to place language in the image control OnSelect.

And I've tried creating a button and using it to open the image. I can't seem to get it straight.

I want the images to continue to appear in the Gallery, and when the image or a button associated with the image is clicked the image open in a larger web view.

@Phineas ,

You need  ThisItem.Value for the item in the gallery. I have a blog on this (section is here).
For the full-screen, just make an image control the size of the screen, with the Visible  as a Variable ( I have used varShow, but call it whatever you want), then on the OnSelect of the image in the gallery

UpdateContext({varShow: true})

Also put an X icon in one top corner, also with the Visible of varShow and the OnSelect

UpdateContext({varShow: false})

Finally the Image of this large control would be

YourGalleryName.Selected.Value

Try this

Launch(ThisItem.AbsoluteUri)

@marytonya ,

That only works after the attachment is saved to the data source - this was about a preview of an unsaved item.
