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

    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)
