Some of JPG files refuse to show up in the ASP page

Although this question does not belong in here, I hope someone help, as I do
not know where to send it, but someone here might have come acros similar
problem:
Some of JPG files sitting in the same folder show up OK on an HTML page,
while the other do not as if they are not there or their name is misspelt.
Tried low-upper case in an ASP page, and in the files names - same result
Then I noticed that the same files do not show up in the preview pane in the
Windows Explorer althought they still are described by Windows Explorer as
valid JPEG files.
These "wrong" files are not necessarily bigger then the good ones and in
Microsoft Photo Editor they all (good and bad) show up well and they all are
118 Pixels/cm and True Color (24 bit)

What might be wrong with these files?
If there is not direct answer, perhaps spmeone recommend me a correct
newsgroup?

I can't find anything wrong with the <img> code - even tried it on my own
server, though I've not seen putting the forward slash at the end very
often. <img src="pic1.jpg"/> as opposed to <img src="pic1.jpg"> .

What version of IIS?
What browser are you using?
If you use a different browser does the problem go away?
What ELSE is going on on the page?

William,
I am sure it has nothing to do with html/asp code as the same code works for
one image and does not for another. Just have a look at the live page in
question:
http://www.electrolube.com/distribut...the_folder.asp

ASP code uses the FileSystemObjec t to read all the filenames in the folder
and then puts these names in the <img> tags so all the images in a folder
are supposed to be displayed. Of course all the <img> tags are absolutely
the same except the filenames. And yet some images do not show up.

Mistakes in the filenames are out of question, unless FSO somehow mis-read
them, but I checked them in the resulting HTML (view source) and everything
is correct including the letter case.
So ther problem is iof the files themselves

Page is missing a DTD, character encoding and title text. The images have
no ALT text.

FWIW: Opera has more luck, but even so has difficulty making an image out
of this: <img src='folder_con tents.asp' border='1'>

I wouldn't assume there is nothing wrong with the code when I see this:

folder_contents .asp 1563
show_all_images _in_the_folder. asp 1345

....and the source is this:

<img src='folder_con tents.asp' border='1'>&nbs p; &nbsp;folder_co ntents.asp
&nbsp; &nbsp;1563<b r>
<img src='show_all_i mages_in_the_fo lder.asp' border='1'>&nbs p;
&nbsp;show_all_ images_in_the_f older.asp &nbsp; &nbsp;1345<b r>

Since you're using IIS 5.0, the names shouldn't be case sensitive and I've
already test that. The files do not have .gif, .png or .bmp extensions so
my only conclusion is that you're pulling the file size from a database and
not actually getting the information directly from the file at run time.
So, either the files that do not show are zero bytes or you've added them to
your site with Visual InterDev or something similar that uses FPSE
(FrontPage Server Extensions) and you're working in master mode and it shows
the files to be there in your editor but they have not been added to the
master web. It will show a blue pennant as the icon next to the file in the
editor.

I have experienced this before when trying to upload a lot of large files
via VI 6.0.

Since the files just do not display instead of generating an error, it
appears they are actually there but they're zero bytes.
Seeing the code might help to prove or disprove it's not something in the
code.

The other thing that would keep it from displaying you're not using which
would be an ID, if you were preloading and using getElementById. It would
load the first image with the ID but any subsequent images with the same ID
would not be loaded.

William...

I tried loading the files that do not display by themselves in the browser
by calling them by name and they do not display that way either. So, I
downloaded one of the files and tried to display it locally in IE, still
nothing. So, I opened the image in Microsoft Photo Editor and resaved it.
Now it shows the image.

Uncompressed the file is almost 2Mb. Compressed the original version was
314Kb and now 35Kb. The image settings are still the same, True
Color(24-bit), width: 666px, height: 999px, uncompressed bytes: 1996002.

You can see them here: http://kiddanger.com/lab/electrolube/images.html
....or at least see the new revision.

William and Ronald,
The bit of the source code you are refering to
<img src='folder_con tents.asp' border='1'>
Is absolutely correct and of cource no image shows up because
folder_contents .asp (as well as show_all_images _in_the_folder. asp) is not an
image but the ASP code.
For the moment it is sitting together with the images, but once the whole
thing is working, I either move it into another forlader or add an IF
statement which would skip over files with .asp extention

The rest image tags are formed like that

<img src='apl400-1.jpg' border='1'>

which seems perfectly OK to me, escept a missing closing "/" which should
not affect the image display. Yet the image fails.

So the problem seems to be with the images?
