Rendering images in Dreamweaver

Hello
I am busy redesigning my site and really want to learn how to display my images like this on my site: http://www.andrewmcgibbon.co.za/
I really like how the image increases as well as renders the image as per the size of browser? I had a look online and could not find any answers!
Does anyone know what the code would be for this?
thanks a million!
Wes

>Should I use relative instead of absolute links?
Yes.
You should not use absolute links unless you are creating a page for an email blast, or whenver your page will be hosted on a server that is not where the resouce is located - an ebay ad for example.
Use either doc or site root relative links.

How to change the bar chart rendering image format in SSRS

Hello all,
I am working with SQL Server 2008 R2 and I have a SSRS bar chart report, when the report got rendered over online or if the take Export (PDF and PPT), the image is in png format always, which is taking too much of time to execute the report in case of large
data.
Can, It be possible that the rendered image is in jpeg format instead of png.
If Yes, please share the appropriate steps to follow:
Thanks in advance
Pankaj Kumar Yadav-

Hi Pankaj067,
According to your description, you want to change the bar chart rendering image format as JPEG format when previewing the report or exporting to a PDF file .
In Reporting Services, the chart rendering image format is PNG by default. It’s a by-design behavior. And it doesn’t open any API for us to change the image type when exporting a chart to a format. So in your scenario, your requirement can’t be achieved
in Reporting Services currently. I would recommend you submit a feature request to Microsoft at this site:
https://connect.microsoft.com/SQLServer. So that we can try to modify and expand the product features based on your needs.
If you have any question, please feel free to ask.
Best regards,

I need help Centering a div box to a background image using dreamweaver cs5.5.

I need help Centering a div box to a background image using dreamweaver cs5.5. Everything shift left when viewing on different size monitors? See what I mean at
www.woodlandhospice.com

Have you looked at your page with images disabled?
I urge you to re-think this approach to web design because images of text are not indexed by search engines, screen readers or translators. Given the demographic group your site is targeting, you really need to ensure maximum web accessibility for all users.
Navigation, headings and descriptions all need to be in real text -- not images of text.
Ken is right. Absolute positioning is pure poison for such a simple layout. My advice is to start over with one of the pre-built Starter Pages in DW. Go to File > New > Blank page > HTML. Select a layout from the 3rd column and hit CREATE button.

Background image in Dreamweaver CS3

When I set my background image in Dreamweaver it shows on the "Design", although when previewed on a browser it does not show. I've checked the directory and it seems fine. What is causing this?

Modify-->Page Properties, Im using css but not for the page background. I tried previewing the page locally and I have tried it on the server. The entire site root folder was uploaded which has the background.

Rendering Image in JPanel

Hi,
I am completely new to java imaging and I am planning to build a small image viewer application (something similar to the comic book reader).
After some search and following the discussion here [http://forum.java.sun.com/thread.jspa?forumID=20&threadID=362429|http://forum.java.sun.com/thread.jspa?forumID=20&threadID=362429] , I have main app consists of JFrame with SplitPane which consists a ScrollPane. In separate class, I have JPanel class. I am trying to add the JPanel in ScrollPane when application starts. JPane is responsible for fetching and rendering image but something went wrong and it is giving me a NullPointer Exceptions. So far I was able to figure out that it is causing by the "paintComponent" method but no idea why. I am looking for a nice suggestions and guidance on this topic (especially something like why it didn't work and various ways to do things). "For Dummies" style suggestions are highly appreciated.
Follwing are my two classes:

You should not call paintComponent explicitly (especially with a null Graphics object).
It is called internally when the component needs to repaint itself.
Read this: [Performing Custom Painting|http://java.sun.com/docs/books/tutorial/uiswing/painting/]

Rendered images are not appearing on the webpage. works fine on IE. All plugins appear to be present includeing Adobe Flash

rendered images are not appearing on the webpage. works fine on IE. All plugins appear to be present including Adobe Flash

If that only happens on a specific page or domain then make sure that you do not block images on that domain.
See [[Images or animations do not show]]
*A way to see which images are blocked is to click the favicon (<i>Site Identification</i> icon) on the left side of the location bar.
*A click on the "More Information" button will open the Security tab of the "Page Info" window (also accessible via "Tools > Page Info").
*Go to the <i>Media</i> tab of that "Tools > Page Info" window.
*Select the first image link and scroll down though the list with the Down arrow key.
*If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.
*You can see the permissions for the domain in the current tab in Tools > Page Info > Permissions
*You can see all image exceptions in Tools > Options > Content: Load Images > Exceptions

Using Background Image In Dreamweaver

Good evening.
I'm using a non-repeating, centered background image in Dreamweaver. But i'd like it to self-adjust its size depending upon what monitor size its viewing it. Can someone provide some coding for help with this???
Here's where i'm at thus far..
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<link href="welcome10.css" rel="stylesheet" type="text/css" media="screen" />

<body style="background-color: #000; background-position: center top; background-repeat: no-repeat; background-image: url(images/girls-bg9.jpg); background-attachment: fixed;">
<div id="wrapper">
          <div id="container">
    </div>
</div>
</body>
</html>
css -
@charset "utf-8";
/* CSS Document */
#wrapper{
          width: auto;
          height: 1600px;
#container {
          background-color: #FFF;
          height: 200px;
          margin-right: 100px;
          margin-left: 100px;
          margin-top: 100px;
thanks guys, and gals...

Background-size would do the trick, but keep in mind, most CSS3 does not function in IE9 (though this will), and won't at all in IE8 and down. If you need it to work in those browsers, the best way to do it would be with javascript. I've used the script available on this site with some success...

Import text image in Dreamweaver

Hi All
I have designed some text headings (which are in colour) with a transparent background in fireworks and exported it (gif) to Dreamweaver. That is all good. But when I place the text image (as a background image) in Dreamweaver the text has (in places) white edges which I dont want. Any ideas why this is happening???
Any advice
Paul

The effect that you're experiencing is known as "jaggies". When exporting from Fireworks, you need to set the Matte colour picker to a similar colour to your background.
A better solution, though, would be to use an embedded web font. You can get a lot of free webfonts from www.fontsquirrel.com. Alternatively, if you're using the Creative Cloud, you have access to a lot of TypeKit fonts.

GeoRaster theme: no rendered images

I have loaded/validated a georaster. It appears fine in the GeoRasterViewer, and the spatial extent appears fine as a vector theme in Mapviewer. But addGeoRasterTheme in my jsp results in the log warning:
"GeoRaster theme [themename] has no rendered images."
Anyone have experience with the root cause of this warning? Does this indicate a problem with the georaster, or a problem with the request? Any feedback is appreciated.

Here's the log. (the 'exception while getting srid...' is a red flag! Hopefully it will lead to my mistake)

Not seeing div background image in Dreamweaver! Why?

I'm not seeing div backgrounds in Dreamweaver! When I load the files onto my server I can see them in my browser! But I'm not seeing them in Dreamweaver. Here's my code on my .aspx pg:
<link href="styles/styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="container">
<div id="hdr">
</div>
</div>
</body>
And here's a link to the web page on my server:
http://amcenergy.com/ee_site1/index.aspx
I need to put text on top of the div's background image, but it's kinda hard if I can't see the background image in Dreamweaver.
Hope someone can help!
Thanks so much!!

Horizontal-align is not a valid CSS property.

Updated to LR 5.4, images now importing extremely slow. After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast.

After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast. Canon,Nikon, Leica and Fuji files all rendering slow. iMac 2.9 ghz 16gb RAM OSX 10.8.5. Catalogs and images are kept on external drives. Drives running fine. Really need a fix on this since I'm norally imported and processing at least 4,000 images per LR Catalog. Is there way to revert back to 5.3? I can't use 5.4 is its current state. Thanks.

Download LR 5.3 and install it
By the way, lots of people have this complaint about LR 5.4, and the advice I give is to use LR 5.3 unless you need one of the new camera models supported by LR 5.4

Trouble with opening images from dreamweaver cs6(64bit) to photoshop cs6(64bit).

I uninstalled and went to preferences/file types editors to set up ps6 as primary but I still get some error.After i click image in dreamweaver,I get this message-Unable to launch...Please be sure that application exists and that there is enough memory to run it..

Can you Launch Photoshop normally from your desktop shortcuts?
I usually keep DW and PS open at all times so I can switch back & forth.
