Menu
I have a webpage generated from python that works as it should, using:
print 'Content-type: text/html\n\n'
print "" # blank line, end of headers
print '<link href="default.css" rel="stylesheet" type="text/css" />'
print "<html><head>"
I want to add images to this webpage, but when I do this:
sys.stdout.write( "Content-type: image/png\n\n" + file("11.png","rb").read() )
print 'Content-type: text/html\n\n'
print "" # blank line, end of headers
print '<link href="default.css" rel="stylesheet" type="text/css" />'
...
All I get is the image, then if I place the image code below my html/text header all I get is the text from the image, ie:
<Ï#·öÐδÝZºm]¾|‰k×®]žòåËÛ¶ÃgžyFK–,ÑôéÓU½zuIÒ}÷ݧ&MšH’V¯^?üð¼1±±±zýõ×%IñññÚºu«*W®¬wß}W.—K3gÎÔÌ™ÿw‹Ú””I’¹w¤¥hdÒd½q÷X•Šˆ²m¿þfïÞ½*]º´éÈs;¥¤¤Ø¿ILLÔˆ#rÊ
Also, if I try:
print "<img src='11.png'>"
I get a broken image in the browser, and browing directly to the image produces a 500 internal server error, with my apache log saying:
8)Exec format error: exec of './../../11.png' failed Premature end of script headers: 11.png

To display image on a HTML page with Python Flask, we can pass the image path to the template from the view. Then we call render_template with the template file name, and the user_image argument set to the image path. to interpolate the user_image in the template.
Use the PIL Module to Display an Image in Python We have the PIL library in Python, which has methods available to store, display or alter images. This method will create an image object and open the required image by specifying its path.
To display an image, use the <img> tag with the src attribute the way you'd use the href attribute in an <a> tag. It's important to provide the width and height of the image upfront to avoid layout issues and jumping visual effect.
You can use this code to directly embed the image in your HTML: Python 3
import base64
data_uri = base64.b64encode(open('Graph.png', 'rb').read()).decode('utf-8')
img_tag = '<img src="data:image/png;base64,{0}">'.format(data_uri)
print(img_tag)
Python 2.7
data_uri = open('11.png', 'rb').read().encode('base64').replace('\n', '')
img_tag = '<img src="data:image/png;base64,{0}">'.format(data_uri)
print(img_tag)
Alternatively for Python <2.6:
data_uri = open('11.png', 'rb').read().encode('base64').replace('\n', '')
img_tag = '<img src="data:image/png;base64,%s">' % data_uri
print(img_tag)
Images in web pages are typically a second request to the server. The HTML page itself has no images in it, simply references to images like <img src='the_url_to_the_image'>. Then the browser makes a second request to the server, and gets the image data.
The only option you have to serve images and HTML together is to use a data: url in the img tag.
