Problems Loading Image Files

[somerbooks]

Hi,

I'm experiencing an intermittent but increasingly prevalent problem loading .jpg files to our web site from Dreamweaver MX.  All other file types load ok with no problems whatsoever but .jpgs either fail to load or take several attempts with timeouts often occurring.

The problem seems somehow worse with small files (i.e. thumbnails) as they appear to load ok then I get the "Waiting for server" message followed by a timeout.

I'm connecting via a wireless link to a home hub using BT Infinity fibre.  Anyone else having the same problem?

Thanks,

Mark

Did you resize the images properly using a graphics editor package like Photoshop,Fireworks or GIMP?

or did you just change the height & width values in Dreamweaver and squash the full size into a thumbnail...

Hi,

Thanks for your reply.

Images are all resized using Fireworks.  Per our posting, the problem is intermittent but has become singnificantly worse over the past few weeks (we've been loading weekly images to our web site for about five years now).

Is there a special form of checksum used when confirming complete receipt of image files that's different to how other files are checked?  We've never had a problem with .htm or any other file formats - just .jpgs.

Well you could try asking over at Stackoverflow.com about the checksum issue. It will be interesting to see what they say and what BT tech support comes back with.. The other thing that could be causing problems is the server configuration, though  its rare for anybody to bump against the max files per folder limit it is posibble.  Vaugely recall a figure of 32,000 for linux systems before performance becomes significantly degraded.

Do you think it depends on what size your .jpg files are? Try downloading or uploading any small .jpg files and see on it goes.

Thanks for the last couple replies- I used to know what "stack overflow" meant, I'll have to go an refresh my memory.

The problem isn't down to maximum directory sizes, at most we only have 300-400 images in any one directory.

Re: file size - the last time this problem occurred we could only load files under 5k and it was bigger files that failed to load, this time it's the smaller files that seem most prone to failure.  The fix the last time was to unfold a paper-clip and press the reset button on our home hub.

I suppose the whole thing could be down to congestion at BT web hosting and the need for them to install a few more servers.  Anyway, I'll see what happens later this week when our latest batch of files are loaded.

Thanks again,

Mark
