I have some experience with Python but none with Flask or any web development. I tried deploying my first app on PythonAnywhere using Flask. It's a very simple script and the "desktop" version works perfectly well. On the site, the image is being generated and saved to file in a static folder ('/static/'). I want the script to show the user the picture automatically once it is generated. The most important thing is that the user must be able to save it. However, when I try: <pre><code>return redirect("http://www.example.com/static/image.png") </code></pre> the image is being displayed properly and can be saved properly using "Save Page as". But when I right click the image and click "save image as", the file it writes is corrupted. It's not even the image (the file size is much larger). The filename is wrong too. Instead of "image.png" it saves it as "enc_text.png" ("enc_text" is the name of the function in my script. How can I get "save image" to work? (I don't want a solution to do with embedding the image on a blank HTML page (e.g., img src="...") Any help is much appreciated. EDIT <pre><code>@app.route('/enc_text', methods=['POST']) def enc_text(): text = request.form['text'] text = unidecode.unidecode(text) filepath = os.path.join(app.config['UPLOAD_FOLDER'],'steg','enc') filename = 'image.txt' targetname = filename.rsplit('.', 1)[0] + '.png' target = os.path.join(app.config['UPLOAD_FOLDER'],'steg','enc',targetname) steg.encode(text, target) #Reads text and returns PNG file return redirect("http://www.mysite.com/static/image.png") </code></pre> (Note: steg.encode is a function I wrote) EDIT It seems to be only a problem with Firefox (23.0.1). The problem persists even when I restart Firefox in Safe Mode. I tried it on IE, Chrome and Safari and both "Save page" and "Save image" works fine. That's weird. I opened the "enc_text.png" using notepad and it contains the following HTML: <pre><code><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <title>405 Method Not Allowed</title> <h1>Method Not Allowed</h1> The method is not allowed for the requested URL. </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
