I have a web app I'm building in Dashcode, currently every thing is working as advertised. I'm using the browser template and was able to modify it a bit, got the xml working to connect images and their description. Now I want to add a simple OnClick event that sends the image to fullscreen but I can't find any documentation for that. I'm pretty sure this is easily done so I'm missing something here? Any help greatly appreciated.

Taking over the screen is a bit complicated (if your talking about a full screen experience like youtube), but full screen in the browser window is defiantly possible. The simplest method is to have the click event open a link to the image location. This would load the image in full resolution in the browser window. A more elegant approach would be to load the image url into the source of a image dashcode object. and have that objects visibility only appear overs the whole web app when the Oncick event occurs. If you are talking about a built in function in dashcode to achieve a full screen/browser image, your out of luck.

I'm new to web development and not sure how to explain this, I'm building a tool with lots of links and features to help making things at a call center easier but I wish everytime the page is opened it resizes to a small rectangular version. Is there a way this can be done? Thanks!!
I have a window.open code to launch inappbrowser on phonegap. I use it for displaying image.
This inappbrowser has EnableViewPortScale=yes, so it's totally zoomable.
However, it seems like there is zoom-out-limit in inappbrowser. Here is the code.
window.open(myFullImageUrl, '_blank',
'location=no,EnableViewPortScale=yes,presentationstyle=pagesheet');
It's already zoomed-in a little. I can zoom-in-and-out because of EnableViewPortScale=yes for sure.
However, it seems like there is zoom-out-limit.
when i load up 1024x768 photo, it doesn't show fully zoomed-out photo(on both iOS and Android), but it's like 120%-ish already zoomed in.
I Just created stackoverflow account, so i can't upload photo. sorry!(it says i need 10 reputations to upload image)
There is no true solution for this issue.
So what I did is I just continue using inAppBrowser, but just instead of directly loading image from Amazon server(that's where I stored all images), I just made my window.open to go to another my URL and attach that url as a parameter after '?'.
The reason why I did this is because then I can force the Image web-view to have brief Javascript and CSS to render this dang-image correctly.
And as you guys know, this page must have meta-data that allows user-scale true, and must NOT have max-scale value.
So, Yep. Long story short, If you DIRECTLY load up the image in the inAppBrowser of phonegap, there is NO WAY you can force the image to start with 'not even slightly zoomed-in, but perfectly zoomed-out to the max'. Your own Page, Your own JS and CSS is the way to go guys.
You all know the Windows Phone backstack right. If you go through some apps, tap the Home key after starting each app. Now tap and hold the Backkey to see the Backstack. You can now see some small images of your apps, and can pick which one to go to right.
Question:
Is it possible to intercept before the backstack image is created? I have tried to blur my page in various events (include OnNavigatingFrom) to no avail.
My guess is some other event (probably something we don't have access to) is triggered and a bitmap is created, because when you use the Backstack to navigate you can just see a slight transition from the saved image to a real page IMO.
Does anyone know if its possible to intercept or manipulate these images on the backstack?

Following my comment, I've just tried this:
Set a breakpoint anywhere in the code
Start the app with the debugger attached, then let it reach the breakpoint
While the execution is stopped by the debugger, long press on the back button
The task switching UI is displayed even though the managed code execution is stopped
From there, I think we can safely conclude that the task switching and the thumbnail are handled entirely by native code. Therefore, there's nothing you can do.
I recently wrote a blogpost in which I discuss the ways I tried to hide data from the application snapshot. (You can read it here: http://corstianboerman.com/trying-to-hide-crucial-data-from-an-application-snapshot/)
The outcome: You just can't hide it.
Anyone know of a Flash file (image) uploader that will force a user to resize and/or crop their image BEFORE uploading it? To then upload it as well.
Basically, I don't want my server processing the image resize/crop. I want to specify a target aspect ratio and have the user resize and crop their image to make it fit.
I've seen cropping uploaders before but they all seem to be server side. I saw a Flex one but I'm not sure it's "mandatory" -- Basically if the user just uploads the image without making edits, then I'd like the Flash to scale and fit the image into set dimensions...Leaving it I guess short in one direction to not stretch.
Anything like this out there?
Thanks!
I have a bounty running with a very similar question, be sure to take a peek - there isn't anything there yet that does client side resizing, though.
Also, SWFUpload is said to support it in the new Beta, but the feature is very sparsely documented right now. You would probably have to work on it to get it running the way you want.

there was another one called resize before upload but the site went down. though while I'm updating this and we're on the subject -- I don't see why you'd want to use Flash these days for this task. There are plenty of JavaScript options and now we also have Google's Dart (which builds JavaScript).
Does anyone know of any free frameworks that help you create thumbnails for web pages, that when clicked, the original image loads ontop of the page (modal like), as oppossed to opening a separate page.
Thanks!
This is really 2 questions in 1. The "lightbox" display of the original, larger sized, images in a modal box is handled in JavaScript with a library such as ThickBox. The resizing of the images can be done manually, or via some kind of code on the server side. Sitepoint has a decent guide on how to resize server side with PHP. I hope this helps point you in the right direction.
Lightbox.

I've used DhoniShow a few times in the past, and clients really liked it. It's not AJAX, as it loads all the full sized images on page load, but if you were motivated I'm sure you could make that change pretty easily.
As have been already said, you can use Lightbox to get the effect to the user, I would use it with its ajax mode, loading the thumbnail as its contents.
Now for the thumbnail, I would recommend you something like http://megasnaps.com/ wich you can use for free.
Good luck.
